Caution

Gravity feed fuel systems may be easier to build and cheaper to buy, but does that mean it’s the smart choice? Due to safety, environmental, and legal concerns, Transfer Flow engineers will not endorse, promote, design, install, or sell gravity feed fuel systems. On gravity feed systems, if the valves, connectors, or fuel lines have any malfunctions there is nothing to stop fuel from overfilling the OEM tank and leaking all over the road.

Transfer Flow Auxiliary Tanks Are NOT Gravity Feed Systems. Our tanks are NEVER to be used in conjunction with gravity feed fuel systems.

Transfer Flow fuel tanks are NEVER to be used in conjunction with fuel tanks made by other tank manufacturers. Our tanks are only compatible with your stock OEM tank or Transfer Flow replacement tank.

The next generation of our TRAX auxiliary fuel tank operating system is here! TRAX
3™ is our computer controlled, self-diagnosing fuel monitoring system that transfers
fuel from your Transfer Flow auxiliary fuel tank to your main fuel tank. The LCD
displays the fuel level percentages in each tank and the operational status of the
fuel system. For your peace of mind, the TRAX 3™ computer module constantly monitors
fuel levels in both tanks.
